"error": {
"code": "serverError",
"message": "cannot get camera info."
}
}
name
can be any of camera.info
, camera.state
, camera.checkForUpdates
,
camera.commands.status
, and camera.commandName
.
code
should be one of the following for 400 status code:unknownCommand
,
cameraInExclusiveUse
, missingParameter
, invalidParameterName
, or
invalidParameterValue
.
message
is defined by manufacturers and is not expected to be a localized
